To @ZZ whom it' may concern.-

Be it known that I, BENJAMIN C. BRADLEY, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Incandescent Vapor-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of referencemarked thereon, in which- Figure 1 is a side elevation showing a portion of the globe broken away and showing parts in vertical section. Fig. 2 is a section on line Z7 b, Fig. 1. Fig. 3 is a section on line a a, Fig. 1. Fig. 4 is a transverse section of `the corrugated thimble, showing the mantle properly located thereon. Fig. 5 is a View showin g the corrugated thimble placed on the burner-tube, also showing a portion of the mantle properly located with reference to the corrugated thimble, showing a portion of the thimble and burner-tube broken away. Fig. 6 is a side elevation showing the top or upper portion of the lamp proper removed. Fig. '7 is a view looking from the right-hand side of Fig. 6, except that the globe is removed. Fig. S is a top View ot' the mixing-chamber, showing the supporting-pipe, also showing top view of feed-chamber. Fig. 9 is a transverse section on line Fig. l. Fig. 10 is a transverse section on line y y, Fig. l. Fig. ll is a bottom or underside view of a screw-threaded iiange, also showing the globe-supporting arms properly located with reference to said flange. Fig. 12 is a view showing the screwfaced flange, also showing the globe-supporting arms and the integral thimble connected to the screw-threaded flange or formed integral with said flange. Fig. 13 is a detached view of one of the globe-supporting arms. Fig. 14 is a View of the float, showing the dierent parts connected to said float to automatically operate the needle. Fig. l5 is a view show- In the accompanying drawings, l represents the supply-pipe, which'is connected to a suitable reservoir of any desired kind or style, which supply-*pipe extends upward between the mantles and is connected at its upper end to the upper end or portion ofthe stand-pipe 2, which stand-pipe is provided with an enlarged portion 3, as shown in Fig. 2, at its upper end, which enlarged portion is connected To one side of the mixing-chamber 4 is located the mixingchamber or passage 6, which chamber or passage is located to one side of the air-conveying tube 5 and is a continuation of the air-conveying tube.

As fue] is conveyed upward through the supply-pipe l, which passes the burner or burners of the lamp proper, gas is produced or generated, which gas is conveyed to the top or upper end of the stand-pipe 2 and on top of the iioat 7, which iioat is located. in the stand-pipe 2, as illustrated in the drawings.

It will be understood that in use when fuel is first supplied to the lamp proper it will ind its way to the bottom of the stand-pipe, which will cause the float to be located at the upper portion of lthe stand-pipe or in substantially the position shown,'it being understood that the rods 8 will prevent said oat from dropping to the bottom or lower end of the stand-pipe in the event the fuel should be removed therefrom and that said iioat is only to have a limited movement'up and down in the stand-pipe, whichlimit'ed movement operates upon the pivoted yoke-lever 9, which pivoted yoke-lever is connected .to the regulating-needle 10. The iioat is so arranged that its normal position will close the needle 10 and cut off the supply of gas, and when the oil below the float has become converted into gas, or a portion of said oil, the iioat may be permitted to fall or move downward, which downward movement carries with it the yokedownward, as illustrated in Figs. 1, 6, and 7.

-end 'of the mantle 23.

lever 9 at the point or place where the rods 8 are connected and throws or forces the downward portion 11 of the yoke-lever9 outward, thereby allowing the gas to escape, as hereinafter described.

For the purpose of closing the needle 10.

the spring 12 is provided, which spring is located and arranged substantially as shown in Fig. 1, and, as shown, it is located between the cap 13 and the end of the needle 10, said needle being provided with the reduced portion 14, around which the spring 12 is lo-l cated. ,Y Y

For the purpose of regulating the tension of the spring 12 the `disk 15 is located in the cap and the screw 16l passed through the cap and against the disk:

As gas is generated it finds its way to the chamber or receptacle 17 and is conveyed from said chamber or receptacle through the passage 1S and into the chamber or passage `6, at which place air comes in contact with the gas and the air and gas conveyed to the mixing-chamber 4f, and for the purpose of providing a means for thoroughly mixing the air and the gas the dellecting-plates 19 and 20 are provided, the plate 2O being located above vthe plate 19 and said plate 2O being rconnected to the mixiug-chamber-t at a point -below the gas-pipe 21, and the plate 19 is vconnected at the opposite side of the mixingchamber, by which arrangement the air and gas are carried first under the plate 19, thence backward over the plate 19 and under the `plate120, and thence forward over the plate 20 and into the gas-pipe 21.

It will be understood that by locating the Vmixing-chamber directly over the burners said mixing-chamber becomes heated, thereby bringing the gas into better condition to be "burned by thoroughly mixing the gas and air together, which mixture is brought about by tracted during its passage through the mixing-chamber.

The gas-tube 21 is extended downward, and its bottom or lower end is connected to the receiving-chamber 22, which receiving-cham- "ber is located below the mantles 23, it being understood that any desired number of mantles may be provided, reference being had-to the number of burners designed to be used.

-From the receiving-chamber 22 extends up- .ward the burner-tubes 24, to which burner- -tubes are connected the corrugated thimbles or bands 25, and over which corrugated thimbles or bands is located the bottom or lower To the receivingchamber 22 is connected the tube 26, which 'tube extends downward through the receiving-chamber and below said receiving-chamber, as illustrated in Fig. 1J Around the tube 2G is located the thim-ble 27, which thimble is provided with the handle 28 and screwthreaded Hange 29, said screw-threaded'iiange and handle being preferably formed integral with thethimble 26.

For the purpose of providing a support for the screw-threaded flange, together with the different parts belonging thereto, the tube 26 is provided at its bottom or lower end with lthe flange 30.

To the `bottom-or under side of the receiving-chamber 22 are pivotally connected the arms 31, which arms extend downward, and to their bottom or lower ends are pivotally connected the globe-supporting arms 32 the outer ends of which are provided with the vupwardly-curved anges 33, which upwardlycurved flanges are for the purposeo'f engaging and holding the globe 34.

The object and purpose of providing the screw-threaded flange 29 is to provide a means for moving the globe-supporting arms back andv forth for the purpose hereinafter described.

When it is desired to remove theglobe 34, the screw-threaded flange 29-is first rotated in the direction that will force the arms 32 outward, after which the globe 34: is slightly elevated, so as to bring the curved ends below the bottom of the globe, after which the screw-threaded ange 29 is rotated inthe opposite direction, which moves the globesupporting arms inward, and when said globesupporting arms have been brought inward a sufficient distance the globe 34 can be moved downward and entirely removed from the lamp proper.

For the purpose of providing a means for starting the lamp the upper side of the top plate 35, which is the upper plate of .the receiving chamber 22, is provided with .the grooves or depressions 36, which grooves or depressions may be arranged and located as shown in Fig. 10, said grooves or depressions being for the purpose of receiving alcohol or light material, which is forced up through the tube 37 by any suitable injector, and for the purpose of `conducting the alcohol to the depressions or grooves the cap 3S is provided, which cap is supported in properposition by means of the connecting bars or feet 39, (see Fig. 10,) and for the purpose of forcing the alcohol away from the top or upper end of the tube 37 the cap 38 is provided with the inverted cone 40, said cone being located and arranged substantially as shown in Fig. 1.

In Fig. 15 I have shown my invention as applied to a stand-lamp. In order'to provide a circulation between the stand-pipe 2 and the feed-pipe 1, said feed-pipe maybe connected to the stand-pipe by means ofthe short tube 41, which short tube connects lthe two pipes together and forms a communication between the stand-pipe and the feed-pipe 1. This rfeature is not illustrated except in Fig. 16;

but it will be understood that when connected as just described the `feed-pipe 1 is to be bent or brought into such a position that it can be connected to the stand-pipe.

For the purpose of providing a means for removing the supply-pipe l for the purpose of removingy any sediment that may collect therein said pipeY is connected by means of the screw-threaded couplings 42 and 43.

The hydrocarbon used in my lamp is kerosene-oil, or what is more commonly known as coal-oil, but it will be understood that' other hydrocarbons may be used without departing from the nature of my invention; but I prefer to use the common kerosene-oil, and the construction above described is Well adapted to the use of common kerosene-oil.

For the purpose of providing asupport for the dome or cap l:L the bars or tubes 2a are provided, said bars or tubes being connected to the top or upper side of the mixing-chamber 4.

lt will be understood that by arrangement of the float the needle lO will not move so as to open its valve until the gas is generated or heated to a high enough temperature to make a very rapid combustion.

It will be understood that many slight modifications may be lnade Without departing from the nature of myin'vention, and hence I do not desire to be confined to the exact construction and arrangement shown and described.

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a feed-pipe connected to and communicating with a stand-pipe, a float located within the stand-pipe, a lever connected to the oat, a needle connected to the lever, an air-supply pipe provided with a chamber at its upper end, a gas-chamber located around the chamber leading from the supply-pipe, a passage leading to the needlechamber, a mixing-chamber provided with plates, one of said plates located below the other and passages formed in the mixingchamber, a gas-conveying tube leading fromthe mixing-chamber to the receiving-chamber, and a burner tube or tubes located above cent to the stand-pipe and provided with a' chamber at its upper end, said chamber located above the stand-pipe, a needle-chamber and a needle located therein, said chamber and needle located at one side of the chamber et, a passage leading from the chamber above the stand-pipe, and a mixing-chamber located above the burners, and the deflecting-plates 19 and 2O located within the mixing-chamber, and a pipe leading from the mixing-chamber to the receiving-chamber, and means for operating the needle, substantially as and for the purpose specified.
